How do I delete my account from a TFS created by me? // team fondation server

I created a test environment, and when trying to access the company's environment it presents the error:

401 Not Authorized

[email protected] has multiple accounts associated with it .

Your work or school account does not have access to COMPANY.visualstudio.com , but your personal account does not have access.

Some Jedi master to help me pls ???
